Product details
Overview
SMCJ6.0AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 1500 W peak pulse power (10/1000 µs), and 10.3 V clamping voltage (VC at 145.6 A). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power supplies.
For engineers reviewing the SMCJ6.0AHM3_A/I datasheet, SMCJ6.0AHM3_A/I pinout, SMCJ6.0AHM3_A/I application, or SMCJ6.0AHM3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 1500 W surge capability, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds VBR to limit downstream voltage to ≤10.3 V. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion during 10/1000 µs surges up to 145.6 A.
The SMCJ6.0AHM3_A/I is rated for TJ = –55 °C to +150 °C, features MSL Level 1 moisture sensitivity, and meets JESD201 Class 2 whisker resistance. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards, supporting lead-free reflow profiles up to 260 °C peak.
Key Specifications

Pinout & Package
SMCJ6.0AHM3_A/I uses the SMC (DO-214AB) package: a 2-terminal surface-mount device with cathode marked by a band on the body. Terminals are matte tin-plated leads compatible with standard reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection in unidirectional TVS configuration | Connected to ground or low-impedance return path; completes clamping loop during overvoltage event |
| Cathode | High-side connection; marked by band | Connected to protected line (e.g., 12 V rail or sensor input); conducts surge current to ground when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Halogen-free & RoHS-compliant | Meets EU RoHS Directive 2011/65/EU and JEDEC JS709C material requirements for green electronics |
| 1500 W peak pulse power | Provides robust protection against ISO 7637-2 Pulse 1, 2a, 3a/b, and IEC 61000-4-5 Level 4 transients |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage stress on downstream silicon-critical for 5 V and 3.3 V logic interfaces |
| MSL Level 1, 260 °C peak | Enables direct placement into standard lead-free reflow ovens without baking or special handling |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 6.0 V.

IC Role / Device Role / Timing Role: TVS connected between sensor output line and ground, with low capacitance preserving signal integrity. Use Value: Sub-1 ns response and <1000 µA leakage at 6.0 V ensure minimal impact on 0–5 V analog signals while suppressing ±8 kV contact ESD. |
| DC-DC Converter Input Stage | Motor Drive Gate Driver Protection |
Use Scenario: Safeguarding buck converter input stages against back-EMF from relay coils or solenoids. IC Role / Device Role / Timing Role: TVS installed across input capacitor to absorb inductive kick energy before it reaches controller IC. Use Value: 145.6 A peak surge current rating handles repetitive 100–500 mA coil switch-offs without degradation. | Use Scenario: Preventing gate oxide failure in N-channel MOSFET drivers due to Miller-induced voltage spikes. IC Role / Device Role / Timing Role: TVS placed between gate and source terminals to clamp overshoot during high dV/dt switching. Use Value: Tight VBR tolerance (±5.3%) ensures consistent clamping onset, avoiding false triggering or delayed protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0AHE3_A/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR range | Not suitable for ISO 7637-2 Pulse 5a (load dump); limited to lower-energy transients | Select when board space is constrained and surge energy is ≤400 W |
| SMCJ6.0AHE3_A/I | Same SMC package and electrical specs, but commercial-grade (E3) without AEC-Q101 or halogen-free certification | Lacks automotive qualification and halogen-free compliance; not approved for under-hood use | Select for cost-sensitive industrial or consumer applications where AEC-Q101 is not required |
Compared with SMCJ6.0AHM3_A/I, SMAJ6.0AHE3_A/I trades surge capacity for compactness, while SMCJ6.0AHE3_A/I sacrifices automotive qualification for lower cost-making SMCJ6.0AHM3_A/I the only option meeting full AEC-Q101, halogen-free, and 1500 W requirements simultaneously.

FAQ
What is the clamping voltage of the SMCJ6.0AHM3_A/I under maximum surge conditions?
The SMCJ6.0AHM3_A/I has a maximum clamping voltage (VC) of 10.3 V when subjected to its peak pulse current (IPPM) of 145.6 A, measured using the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 and reflects worst-case clamping behavior under full 1500 W surge loading. The SMCJ6.0AHM3_A/I maintains this performance across its qualified temperature range (–55 °C to +150 °C).
Is the SMCJ6.0AHM3_A/I suitable for automotive applications?
Yes, the SMCJ6.0AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix, indicating halogen-free, RoHS-compliant construction and full automotive stress testing-including HTGB, HTRB, temperature cycling, and ESD. It is explicitly designed for under-hood and ECU applications subject to ISO 7637-2 and ISO 16750-2 transients. The SMCJ6.0AHM3_A/I meets all requirements for deployment in automotive power distribution and signal protection networks.
How does the SMCJ6.0AHM3_A/I differ from the SMCJ6.0AHE3_A/I variant?
The SMCJ6.0AHM3_A/I differs from SMCJ6.0AHE3_A/I in three key ways: it uses halogen-free molding compound (HM3 vs. E3), is AEC-Q101 qualified (vs. commercial grade), and carries stricter process controls for automotive use. Electrically, both share identical VWM, VBR, VC, and PPPM specs-but only the SMCJ6.0AHM3_A/I is approved for automotive production. The SMCJ6.0AHM3_A/I also complies with JESD201 Class 2 whisker resistance.
What is the thermal resistance of the SMCJ6.0AHM3_A/I, and how does it affect PCB layout?
The SMCJ6.0AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under 6.5 W steady-state dissipation, designers must provide adequate copper area and airflow. For repeated surge events, thermal mass and pad connectivity directly influence safe duty cycle-underscoring why the SMCJ6.0AHM3_A/I datasheet specifies exact pad dimensions.
Does the SMCJ6.0AHM3_A/I have polarity marking, and how is it oriented on the PCB?
Yes, the SMCJ6.0AHM3_A/I is unidirectional and features a cathode band printed on the device body-consistent with DO-214AB standard orientation. During PCB layout, the banded end must connect to the line being protected (e.g., 12 V rail), while the anode connects to ground. Reversing polarity renders the device non-functional for overvoltage suppression. The SMCJ6.0AHM3_A/I's polarity marking is laser-etched and visible under standard AOI inspection.
